23、er many of our cities is a reminder of the polluted air that we breathe.

But simply 29 to electric cars will not mean pollution-free cities. The level of em
26、issions they cause will depend on how the electricity to run them is 30 , while brakes, tyres and roads all create tiny airborne 31 as they wear out.Across the developed world, car use is in decline as more people move to city centers, while young people especially are 32 for other means of travel.

30、swer the question by marking the corresponding letter on Answer Sheet 2.How Much Protein Do You Really Need?A The marketing is tempting: Get stronger muscles and healthier bodies with minimal effort by adding protein powder to your morning shake or juice drink. Or grab a protein bar at lunch or for
31、a quick snack. Today, you can find protein supplements everywhereonline or at the pharmacy, grocery store or health food store. They come in powders, pills and bars.With more than $12 billion in sales this year, the industry is booming and, according to the market research company, Grand View Resear
32、ch, is on track to sell billions more by 2025. But do we really need all this supplemental protein? It depends. There are pros, cons and some ho-hums to consider.B For starters, protein is critical for every cell in our body. It helps build nails, hair, bones and muscles. It can also help you feel f
33、uller longer than eating foods without protein. And, unlike nutrients that are found only in a few foods, protein is present in all foods. “The typical American diet is a lot higher in protein than a lot of us think,” says registered dietitian Angela Pipitone. “Its in foods many of us expect, such a
34、s beef, chicken and other types of meat and dairy. But its also in foods that may not come immediately to mind like vegetables, fruit, beans and grains.”C The U.S. governments recommended daily allowance (RDA) for the average adult is 50 to 60 grams of protein a day. This may sound like a lot, but P
35、ipitone says: “We get bits of protein here and there and that really adds up throughout the day.”Take, for example, breakfast. If you ate two eggs topped with a little bit of cheese and an orange on the side, you already have 22 grams of protein. Each egg gives you 7 grams, the cheese gives you abou
36、t 6 grams and the orangeabout 2 grams. Add a lunch of chicken, rice and broccoli, and you are already over the recommended 50 grams. “You can get enough protein and meet the RDA before you even get to dinner,” says Pipitone.D So if its so easy to get your protein in food, why add more in the form of
37、 powders, snack bars or a boost at your local juice bar? No need to, says Pipitone because, in fact, most of us already get enough protein in our diet.“Whole foods are always the best option rather than adding supplements,” she says, noting the FDA does not regulate supplements as rigorously as food
38、s or drugs.So there could be less protein, more sugar and some additives you wouldnt expect, such as caffeine.E If you are considering a supplement, read the list of ingredients, she says, although this is not always reliable. “Ive seen very expensive protein supplements that claim to be high qualit
39、y but they might not really be beneficial for the average healthy adult,” she says. “It could just be a waste of money.”F But there are certain situations that do warrant extra protein. “Anytime youre repairing or building muscle,” Pipitone says, such as if youre an extreme endurance athlete, traini
40、ng for a marathon, or youre a body builder.If youre moderately exercising for 150 minutes a week, as the Centers for Disease Control and Prevention recommends, or less than that, youre probably not an extreme athlete.Extreme athletes expend lots of energy breaking down and repairing and building mus
41、cles. Protein can give them the edge they need to speed that process.G Vegans can benefit from protein supplements since they do not eat animal-based protein sources like meat, dairy or eggs. And, for someone always on-the-go who may not have time for a meal, a protein snack bar can be a good option
42、 for occasional meal replacement.Also, individuals recovering from surgery or an injury can also benefit from extra protein. So, too, can older people. At around age 60, “muscles really start to break down,” says Kathryn Starr, an aging researcher, “and because of that, the protein needs of an older
43、 adult actually increases.”H In fact, along with her colleague Connie Bales, Starr recently conducted a small study that found that adding extra protein foods to the diet of obese older individuals who were trying to lose weight strengthened their muscles. Participants in the study were separated in
44、to two groupsone group was asked to eat 30 grams of protein per meal in the form of whole foods. That meant they were eating 90 grams of protein a day. The other groupthe control groupwas put on a typical low-calorie diet with about 50 to 60 grams of protein a day.After six months, researchers found
45、 the high protein group had significantly improved their muscle functionalmost twice as much as the control group.“They were able to walk faster, had improved balance, and were also able to get up out of a chair faster than the control group,” Starr says.All 67 participants were over 60 years of age
46、, and both groups lost about the same amount of weight.I Starr is now looking into whether high-protein diets also improve the quality of the muscle itself in seniors. Shes using CT scans to measure muscle size and fat, and comparing seniors on a high-protein diet to those on regular diets. She says
47、 her findings should be available in a couple of months.J In the meantime, 70-year-old Corliss Keith, who was in the high protein group in Starrs latest study, says she feels a big difference. “I feel excellent,” she says. “I feel like I have a different body, I have more energy, Im stronger.” She s
48、ays she is able to take Zumba exercise classes three times a week, work out on the treadmill, and take long, brisk walks. Keith also lost more than 15 pounds. “Im a fashionable person, so now Im back in my 3-inch heels,” she says.K As people age, Starr says muscle strength is key to helping them stay strong and continue living on their own in their own home. “I feel very much alive now,” says Keith. “I feel like I coul
